My guess is that the "communication" is fairly basic (e.g. position, speed, acceleration - nothing a human driver couldn't observe), rather than information about strategies (e.g. "I am going to attempt to overtake on the inside at the next turn"). Done right, I could see this event being quite spectacular. Vehicles could take bigger risks, and reap bigger rewards (and bigger crashes).
